Martin hangs on to lead at Q-school

ORLANDO, Fla. 
Ben Martin and James Driscoll continued to post rounds in the 60s at PGA Tour qualifying school Saturday and moved two rounds closer to earning their tour cards for next year.

Marin had a 69 on the Crooked Cat course at Orange County National and had a one-shot lead over Driscoll, who had a 66 on the same course. Martin was at 270 through four rounds of the six-round tournament.

The top 25 will earn PGA Tour cards for 2011.

Billy Mayfair posted his fourth straight round in the 60s with a 68. He was tied for fourth, only four shots out of the lead. The difference between Martin and the final spot was eight shots.

Brett Waldman, the caddie for Camilo Villegas, had a 72 and was tied for 59th, three shots behind the cutoff. After the top 25, the next 50 get cards on the Nationwide Tour.
